SPECIFICATION forming part of Letters Patent No. 241,243, dated May 10, 1881.

Application filed August 11, 1879.

To all whom it may concern:

Beit known that I, J onANNns SELWIG, engineer, of Brunswick, Empire of Germany, have invented a new and useful machineviz., a continuously-working press, called by me conepress"-for pressing substances that contain a fluid of any kind, in order to remove or to gain that fluid; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation ofthe same, reference being had to the annexed drawings, making` a part of' this specilication.

Figure l represents a longitudinal section; Fig. 2, a transverse section of the press on the line .t y x' y' a y2; Fig. 3, a longitudinal, and Fig. 4c a side, elevation ot the same.

The principal parts of the press are two circular pressing-disks, A and A', with slightlyconical surfaces a c j C and a' c' j" C', inclosed at their peripheries by a strong casin g, C and C', the disks revolving slowly in the same direction about two fixed axes, B and B', connected with the casing, and being slightly inclined to each other in the plane x' y', Figs. l and 3, as clearly shown by Fig. 2. 0n account ot' this inclination the conical surfaces of' the pressing-disks, which have such a position that the vertexes of the cones are lying in the same point, are more distant from each other at their upper than at their lower part, the maximum of the distance lying at Q, Fig. l, the minimum at Q', both in the plane w' y', opposite eachother. From Q to tb' the distance ofthe surfaces graduallyr diminishes at both sides. The pressing disks, which are strengthened by ribs and provided with a toothed rimp and p', near their periphery, have a great number of holes cast into them. Their conical surfaces are connected and covered with perforated metal plate. The casing inclosing them is composed of two parts, C and C', joined by screw-bolts t, the central parts of which form the hollow axes B and B', about which the disks revolve. The casing has two large openings, g h and ik, in its mid-` dle part. Through the first, g h, which is provided with a feeding-hopper, R, the substance to be pressed is passed into the space between the disks. Through the latter,i 7c, the pressed mass leaves the press.

Two fixed partitions, e and w, firmly united to the outer casing on the one hand and the axes'on the other, separate the space within the press in a nearly radial direction.

The disks are set into motion by two pinions, K and K', with oblique teeth, fixed on the shaft L, working with the toothed rims p and p'. The shaft L is driven by two pairs of spur wheels, M and M', from the shaft N, driven by a pulley, l). y

The press works as follows: The substance to be pressed is continuously passed into the hopper It. Having entered the space between the pressing-disks at Q', where their distance is greatest, it is carried along with them by friction in the direction of the revolution indicated bythe arrow E. Since the distance of the disks is smaller at E than at Q, and least at Q', a compression or a pressing out of the substance takes place while it follows the direction Q E Q'. The fluid contained in it is forced through the perforated plate covering the disks, and through the holes cast into the latter, and flows down along their outer sides to the bottom of the casing, which it leaves through the Y-shaped pipe n. The pressed mass, after having passed Q', is pressed forward by the mass following it, and, being prevented from further rotating with the disks by the fixed partition fw, it leaves the press through the opening t' 7c in a direction nearly parallel to w, (indicated by the arrow D.)

The pressure exercised bythe disks upon the substance during the process of pressing drives them asunder ou the other hand, and is taken up by three strong screw-bolts, l, joining the axes B and B', and, besides, by six conical rollers, m and m', three and three placed at each side of the casing, upon which the outer rims of the pressing-disksp and p roll.

The press, as represented, is design ed for removing the water from sliced beet-root which has been extracted by diffusion. It is, in gen-V eral, made of cast'iron.

The conepress invented by me may also be employed for removing the water from paperpulp, wet wool or cotton, and similar substances, or for gaining a part of the juice from squeezed or ground fruits-as grapes, apples, pears, roots, and others 5 or for extracting the oil from oil-fruits-as olives, seeds, 85e. According to its uses, it may be made of any other metal or material adapted to it ICO Having thus described 1n y invention, what 2.
